百色地区城市壮族学生体质发育及发展趋势

The body constitution development and the developmental trends in urban students of Zhuang nationality in Bose Prefecture

目的 研究广西百色地区城市壮族学生体质发育及动态发展趋势。方法 对 2 0 0 0年 7～ 1 8岁 2 4 0 0名壮族学生的身高、坐高、体重、胸围、肩宽和骨盆宽的数据进行统计分析 ,并与汉族学生的身高和体重作比较 ,与城市壮族不同年代学生的身高、体重和胸围也进行了比较。结果 城市壮族学生多数指标显示以 7～ 1 3岁为生长加速期 ,1 4岁以后逐渐减缓。城市壮族学生多数年龄组的身高体重均值比汉族的小。 1 985～ 1 991年壮族学生的身高体重有较大的增长 ,1 991～2 0 0 0年城市壮族学生身高体重多数年龄组有所增长。结论 百色地区城市壮族学生发育指标均随年龄的增长而递增 ,逐年呈现出稳步增长态势 ;城市壮族学生体质发育及发展比汉族学生差。 1 5～ 1 8岁年龄组学生的体质发育及发展呈停滞或倒退趋势 ,因此减负和进行教育教学模式的改革势在必行。

Objective To explore the body constitution development and the dynamic developmental trends of urban students of Zhuang nationality in Bose, Guangxi. Methods All the data of body height, sitting height, weight, circumference of chest, shoulder width and pelvic width in 2400 urban students of Zhuang nationality aged from 7 to 18 in the year of 2000 were statistically analysed. The outcomes of the body height and weight were compared to those of the students of Han nationality, moreover, the data of body height, weight and circumference of chest were compared to those of Zhuang students in different times. Results The developmental accelerating period was at the age of 7 to 13 in urban students of Zhuang nationality, and the growth slowed gradually after 14 years old. The mean value of the body height and weight in urban students of Zhuang nationality in most groups were smaller than those of the urban students of Han nationality. In 1985 and 1991,the growth of the body height and weight in Zhuang students increased greatly. The body height and weight elevated at a certain level in urban students of Zhuang nationality in majority of different ages between 1991 and 2000. Conclusions In urban students of Zhuang nationality in Bose prefecture, their developmental indexes steadily increased as they grew up each year. And their body constitution development and the developmental trends were worse than those in urban students of Han nationality. The body development and its developmental trends were fallen short between the age of 15 and 18, so it is urgent to lessen the students' study tasks and to carry on teaching reform.
